Simpson SSTB36 Anchor Bolt 7/8 in. x 36-7/8 in. is engineered for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie Strong-Wall shearwalls. Backed by extensive testing to determine design load capacity across many common applications, this anchor bolt is code listed by ICC-ES under the 2012, 2015, 2018, and 2021 IBC and IRC - making it a trusted structural fastener for residential and commercial concrete construction. Suitable for both monolithic and two-pour concrete applications, the SSTB36 delivers installation flexibility without sacrificing structural integrity.

Key Features

• Identification on the bolt head showing embedment angle and model - lets installers quickly confirm the correct bolt and orientation on the jobsite, reducing the risk of errors during placement.
• Offset angle reduces side bursting and provides more concrete cover - helps protect the surrounding concrete from stress damage and keeps the installation within code-required cover distances.
• Rolled thread for higher tensile capacity - cold-rolling the threads strengthens the steel rather than cutting away material, resulting in a more capable connection under tension loads.
• Stamped embedment line aids installation - gives crews a clear visual reference for proper embedment depth, helping ensure consistent, code-compliant placement without additional measuring.
• Suitable for monolithic and two-pour concrete applications - supports a wider range of foundation and slab construction methods so one bolt model works across multiple jobsite scenarios.

Why This Product

• Extensively tested for structural confidence - Simpson has conducted thorough testing to establish design load capacities across many common applications, giving engineers and contractors verified performance data to design against.
• Multi-code listed for broad project eligibility - ICC-ES listing under the 2012, 2015, 2018, and 2021 IBC and IRC means this anchor bolt meets the requirements for a wide range of current and recent code cycles, simplifying plan approval on both residential and commercial projects.
• Purpose-built geometry improves concrete protection - the offset angle design actively reduces side bursting forces and increases concrete cover, addressing two common failure points that straight anchor bolts can introduce in tightly reinforced concrete foundations.
• Made to ASTM F-1554, Grade 36 steel standards - specifying a recognized material standard means the bolt meets defined mechanical properties, giving structural designers a reliable baseline for connection calculations and inspectors a clear compliance reference.
